This is an example based on mbed-os cellular APIs that demonstrates a TCP or UDP echo transaction with a public echo server. Especially, BG96 operation check based Mbed OS 5.11, tested via SK Telecom in Korea
This code could be access via Cat.M1(BG96 module) of SK telecom network in Korea. Need a WIZnet BG96 board and development board. Before using this code, must be checking your modem is authorized or not from SK telecom. This code is based on Mbed OS 5.11.5.
Tested with
- DISCOVERY_L485VG_IOT01A
- K66F
- K64F
1. Import the application into your desktop
mbed import https://os.mbed.com/users/Daniel_Lee/code/mbed-os-example-cellular-BG96_os511/ cd mbed-os-example-cellular-BG96_os511
2. Compile and program
mbed compile -t <toolchain> -m <TARGET_BOARD>
(supported toolchains : GCC_ARM / ARM / IAR)
3. Download binary to a target board
